Product Overview

The Cylindrical Grinding Machine for CNC Broach (Model MK8332L-2000) from Zhejiang Quanshun Machine Tool Co., Ltd. is a precision toolroom-grade machine purpose-built for grinding long, slender cutting tools such as broaches, mandrels, and precision shafts. Fitted with a CBN grinding wheel and a servo-driven special headstock, it is engineered to deliver the tight roundness, cylindricity, and surface finish tolerances that broach and cutting-tool manufacturing demands. With a 2000mm max grinding length, 2200mm center distance, and a two-level taper worktable, this machine covers both long straight-shaft grinding and precision taper correction in a single setup.

Key Advantages for Industrial Buyers

CBN Wheel for Hardened Tool Steel — The machine is equipped with a Φ500xBx203 CBN (cubic boron nitride) grinding wheel, ideal for grinding hardened tool steels used in broaches and cutting tools, offering longer wheel life and consistent stock removal versus conventional abrasives.

High-Speed Grinding, up to 100m/s — A linear wheel speed of ≤100m/s — more than double that of standard cylindrical grinders — enables faster stock removal while maintaining a fine, consistent surface finish.

Servo Special Headstock — A dedicated servo-driven headstock (MT5 taper, 60–300r/min) provides precise, stable rotational control specifically suited to long, slender tool blanks that are sensitive to vibration and deflection.

Two-Level Taper Worktable — The worktable swivels clockwise 3° / counterclockwise 3° across two adjustable levels, allowing fine taper correction and straightness control critical to long broach and mandrel geometry.

Toolroom-Grade Precision — Achieves roundness ≤0.002mm, cylindricity ≤0.005mm, and surface roughness ≤Ra 0.2μm — finer tolerances than standard production cylindrical grinders, matching the accuracy demanded by precision tool manufacturing.

Full Servo Axis Control — Both the worktable and transverse feed mechanism use AC servo motors (16Nm torque) with 0.001mm resolution, ensuring repeatable positioning accuracy across long grinding passes.

Applications

This machine is purpose-built for precision cutting-tool and tool-steel component grinding, including:

CNC broaches and broaching tools Long mandrels and arbors
Precision tool steel shafts Cutting tool blanks and reamers
Toolroom and die-making precision shafts

Why Choose Zhejiang Quanshun Machine Tool

Zhejiang Quanshun Machine Tool Co., Ltd. designs the MK8332L series specifically for the tight tolerances required in broach and precision cutting-tool manufacturing. By combining a CBN grinding wheel, a servo special headstock, and a two-level taper worktable, the machine delivers toolroom-grade roundness, cylindricity, and surface finish on long, slender workpieces. We support custom configurations for grinding length, wheel specification, and headstock speed range, along with technical consultation, installation guidance, and after-sales support.

Frequently Asked Questions

Why does this machine use a CBN wheel instead of a conventional abrasive wheel?

CBN (cubic boron nitride) wheels are better suited to grinding hardened tool steel, which is common in broaches and cutting tools. They maintain their shape and cutting ability longer, supporting more consistent precision over extended production runs.

What size and length of workpieces can this machine handle?

The machine grinds diameters from Φ8mm to Φ320mm, with a maximum grinding length of 2000mm, a 2200mm center distance, and a maximum workpiece weight of 150kg.

What precision level can this machine achieve?

It achieves roundness ≤0.002mm, cylindricity ≤0.005mm, and surface roughness ≤Ra 0.2μm, meeting the tolerance requirements of precision tool and broach manufacturing.

What is the maximum wheel linear speed?

The grinding wheel runs at up to 100m/s linear speed, supporting efficient material removal while preserving surface finish quality.

Can this machine grind tapered profiles as well as straight shafts?

Yes. The two-level taper worktable swivels clockwise 3° and counterclockwise 3°, allowing precise taper grinding and straightness correction in addition to standard cylindrical grinding.

Can specifications be customized?

Yes. Zhejiang Quanshun Machine Tool offers customization of grinding length, headstock speed range, wheel specification, and other parameters based on specific tool or workpiece requirements.
